DS_MM32F103xx_o_Ver1.13

Specification

Compatible with ISO7816 smart card mode. The UART interface supports output data

lengths of 5 bits, 6 bits, 7 bits, 8 bits, and 9 bits.

All UART interface can be served by the DMA controller.

2.2.18 I2C interface

The I2C interface can operate in multimaster or slave modes. It can support Standard

mode,and Fast Mode.

It supports 7-bit and 10-bit addressing modes, multiple 7-bit slave addresses (two ad-

dresses, one with configurable mask).

2.2.19 Serial peripheral interface (SPI)

The SPI interface, in slave or master mode, can be configured to 1

∼ 32 bits per frame.

All SPI interface can be served by the DMA controller.

2.2.20 Universal serial bus (USB)

The microcontroller embeds a USB device peripheral compatible with the USB full-speed

12 Mbs. The USB interface implements a full-speed (12 Mbit/s) function interface.The

dedicated 48 MHz clock is generated from the internal main PLL (the clock source must

use a HSE crystal oscillator).

2.2.21 Controller area network (CAN)

The CAN is compliant with specifications 2.0 A and B (active) with a bit rate up to 1 Mbit/s.

It can receive and transmit standard frames with 11-bit identifiers as well as extended

frames with 29-bit identifiers.

2.2.22 General-purpose inputs/outputs (GPIO)

Each of the GPIO pins can be configured by software as output (push-pull or open-drain),

as input (with or without pull-up or pull-down) or as peripheral alternate function. Most of

the GPIO pins are shared with digital or analog alternate functions. The I/O configuration

can be locked if needed following a specific sequence in order to avoid spurious writing

to the I/Os registers.

2.2.23 Analog-to-digital converter (ADC)

The one 12-bit analog-to-digital converters is embedded into microcontrollers and the ADC

shares up to 10 external channels, performing conversions in single-shot or scan modes.

In scan mode, automatic conversion is performed on a selected group of analog inputs.

The ADC can be served by the DMA controller.

The analog watchdog function allows very precise monitoring of all the way, multiple or
